Cycloconverter generator

Abstract

In a cycloconverter generator equipped with an AC power generator that generates single-phase AC power to be supplied to a load by turning on positive and negative switching elements at variable timing every half-period of a desired AC power frequency based on a phase signal and a DC power generator that generates DC power by turning on the positive switching elements in accordance with a timing determined by desired DC voltage, there is installed with a selection switch that is installed to be operable by an user and produces an output indicative of a result of the user's selection between the AC power and DC power thereby enabling to the user to easily select either one of alternating current and direct current.

1. A cycloconverter generator equipped with a magneto having three-phase output windings, single-phase output windings facing the permanent magnets to produce phase signals each indicative of a phase of the output of the magneto, a bridge circuit comprising positive and negative switching elements bridge-connected in antiparallel connection to the three-phase output windings to constitute a cycloconverter, and an AC power generator that generates single-phase AC power to be supplied to a load by turning on the positive and negative switching elements at variable timing every half-period of a desired AC power frequency based on the phase signal, comprising:
 a DC power generator that generates DC power to be supplied to the load by turning on one of the positive and negative switching elements in accordance with a timing determined by desired DC voltage based on the phase signal; and 
 a selection switch that is installed to be operable by an user and produces an output indicative of a result of the user's selection between the AC power and the DC power. 
 
     
     
       2. The cycloconverter generator according to  claim 1 , further including a control panel disposed with a DC outlet and an AC outlet;
 and the selection switch comprises: 
 an outlet cover adapted to be slidable between the DC outlet and AC outlet to block either one of the outlets from being connected; and 
 an electrical contact adapted to produce a signal when pressed by the outlet cover. 
 
     
     
       3. A method of controlling a cycloconverter generator equipped with a magneto having three-phase output windings, single-phase output windings facing the permanent magnets to produce phase signals each indicative of a phase of the output of the magneto, a bridge circuit comprising positive and negative switching elements bridge-connected in antiparallel connection to the three-phase output windings to constitute a cycloconverter, and an AC power generator that generates single-phase AC power to be supplied to a load by turning on the positive and negative switching elements at variable timing every half-period of a desired AC power frequency based on the phase signal, and a DC power generator that generates DC power to be supplied to the load by turning on one of the positive and negative switching elements in accordance with a timing determined by desired DC voltage based on the phase signal; characterized by the step of:
 allowing an user to select one between the AC power and the DC power. 
 
     
     
       4. The method according to  claim 3 , further including the step of:
 blocking either one of the AC power and the DC power from being connected.
